Program

This program involves updating an indexed file. You will start with an indexed file of students and their information, stumasti.datand you will produce a modified Stumasti.dat based on transactions in a file crsereg.dat. This is a "course registration" file that contains grade updates for the students in stumasti.dat. There is a possibility that some of the student grade updates appearing in crsereg.datdo not correspondent to a student in stumasti.dat. If that is the case, then you will write these transactions into a file errrpt.prn. To help you out with this task, I am providing a file Indexed-to-Sequential-Conversion.cbl that, when properly embedded in a project, will convert an indexed file (which is not readable with a text editor) into a sequential file (that you can read with a text editor. This should be helpful to 1) view the original indexed file as a sequential file and 2) view the modified indexed file as a sequential file.

For each student appearing in crsereg.dat and also in stumasti.dat, you need to do the following update:

If the Grade achieved, CR-SEMESTER-GRADE, is not an F, addCR-COURSE-UNITStoSM-UNITS-COMPLETED, otherwise add nothing.

You will need to convert a grade achieved into its numeric equivalent, A = 4, B = 3, C = 2, D = 1, F = 0.

Then you will (for any grade achieved) computeGRADE-POINTS asNUMERIC-GRADE * CR-COURSE-UNITS

Then you will addGRADE-POINTStoSM-TOTAL-GRADE-POINTS.

The updated record is put into the stumasti.dat file using a REWRITE command.

The error file, errrpt.prn, should look as follows:
